I’m Alexander Peppe, a piano technician in Southern Maine. I tune and repair acoustic pianos, and troubleshoot digital pianos and Yamaha Disklaviers. I also help owners farther away with floppy-disk transfers and mail-in repairs.

Piano tuning is the most frequent and essential aspect of proper piano care. Pianos go out of tune as humidity changes. Here in Maine, humidity is highly unpredictable: Constant small fluctuations in humidity mean your piano can go out of tune even more quickly than in other parts of the country. See my Piano Tuning FAQ page for more!
Yamaha Disklaviers
I provide authorized service for Yamaha Disklavier player pianos, including repairs, upgrades, networking, and floppy/USB song support. My Yamaha Disklavier FAQ covers common problems. I also have articles on upgrade options, Internet setup, disk preservation, and compatible song sources.
I also write software for working with these instruments. APS MIDI Prep Tool handles music files and older disks; APS NoteCast lets you play and record MIDI on Android.
Keyboard, Digital, and Electric Piano Service
I perform authorized service on Yamaha, Roland, and Casio keyboards and digital pianos. For information about keyboard and digital piano repair, please see my Digital Keyboard FAQ.
I also provide local service for electric pianos such as Rhodes and Wurlitzer, including rebuilds using components from Vintage Vibe and Tropical Fish.
